Using port-to-port commodity flow data, I find that routes where both ports have RORO trade 23% more than predicted by the individual effects alone. I also propose an interaction event study to investigate the dynamic effects and find evidence that these effects show zero pretrends and have positive dynamic effects. I embed these estimates in an Eaton-Kortum model with island geography and show that complementarity generates a superadditivity premium, implying coordinated port investments dominate sequential upgrades.", "occurrence_notes":null, "guid":"151812-21912220@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/151812", "building_id":"1005177", "building_name":"North Quad", "campus_maps_id":"553", "room":"4325", "location_name":"North Quad", "has_livestream":0, "cost":"", "tags":["International","seminar","Economics"], "website":"http:\/\/www.lsa.umich.edu\/econ", "sponsors":[ { "group_name":"Department of Economics", "group_id":"3302", "website":"http:\/\/www.lsa.umich.edu\/econ" }, { "group_name":"International Economics", "group_id":"3550", "website":"" }, { "group_name":"Department of Economics Seminars", "group_id":"3566", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/09\/event_151812_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2026\/09\/event_151812_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/09\/event_151812_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/09\/event_151812_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/09\/event_151812_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/09\/event_151812_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/09\/event_151812_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/09\/event_151812_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/09\/event_151812_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/09\/event_151812_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/09\/event_151812_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/09\/event_151812_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/09\/event_151812_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/09\/event_151812_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/09\/event_151812_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/09\/event_151812_original-1.png" }, "occurrence_count":1, "first_occurrence":21912220 } , "152024-21912635": { "datetime_modified":"20260911T131259", "datetime_start":"20260917T120000", "datetime_end":"20260917T160000", "has_end_time":1, "date_start":"2026-09-17", "date_end":"2026-09-17", "time_start":"12:00:00", "time_end":"16:00:00", "time_zone":"America\/Detroit", "event_title":"\u201cWho Counts?
